To aZZ whom t may concer/n .f y

Be it known thatl, MARTIN P. CoNNoLLY, a citizen of the United States,residing at Parkersburg, in the county of Wood and State of WestVirginia., have invented new and useful Improvements in Typewriter-Oabinets, of which the following is a speciL cation.

This invention relates to that class of typewriter cabinets having aswinging top and typewriter-supporting platform which are so connectedthat when the top is swung back the platform rises out of the cabinet toplace the typewriter in position for use, whereas when the top is swunginto position to serve as a desk top, the platform swings back into thecabinet beneath said top.

rlhe invention has for its object to provide a novel and improvedoperating connection between the top and the platform, which is strongand durable, and which can be readily assembled, and also to provide aconstruction which enables the platform to be readily removed from thecabinet without disturbing the construction.

With the object stated in view, the invention consists in a combinationand arrange ment of parts to be hereinafter described and claimed, andwhile the preferred embodiment of the invention has been disclosed, itwill be understood that various changes and modifications may be madewithout departure from the spirit and scope of the invention as claimedhereinafter.

In order that the invention may be better understood, reference is hadto the accompanying drawings forming a partof this specification, and insaid drawings,

Figures 1 and 2 are sectional views of the cabinet with the parts indifferent positions;

Fig. 3 is a section on the line 3-3 of Fig. 2;

, Fig. 4: is a detail in perspective;

Fig. 5 is an elevation of a sectional bearing member;

Fig. 6 is an elevation of one of the sections of said member and,

Fig. 7 is a vertical section on the line 7--7 of Fig. 5.

Referring specifically to the drawings,the cabinet has a stationary top9, a bottom 10, a rear wall 11 and side walls 12. The stationary top hasan opening to accommodate a swinging top 13, which latter, when it is 1nraised position, is flush with the former so as to be a continuationthereof and to serve as the top of a writing desk.

The swinging platform which supports the typewriter is shown at 14. Ontop of thisy platform is mounted a slide 15 for holding the typewriter,and to the bottom of the platform, at the side edges thereof are securedangular metal bars 16 mounted to seat over the corners thereof. One ofthe flanges of each angle bar has an outstanding pivot pin o r trunnion17, the pivot pins of the respective angle bars being in alinement andprojecting outward with respect to the side edges to seat in bearings onthe side walls 13 of the cabinet.

Thebearing's for the trunnions 17 are each composed of` two separabletop and. bottom sections 18 and 19, respectively. The section 19 is onan attaching or base plate 20, and the section 18 is on a plate 21. Theplate 2O is secured to the wall 12 by screws or other suitablefasteners, and the plate 21 is detachably and slidably connected to theplate 20. The plate 21 has a vertical slot 22, and a screw 23 is passedthrough this slot and threaded into the plate 20, there being a boss 24on the back of the latter to obtain enough material for a screw hole. Bymeans of the screw 23 the plate 21 is securely clamped to the plate 2Oto hold the two bearing sections 18 and 19 in assembled relation. Upontaking the screw out, the plate 21 can be slid upwardly to remove theupper half 18 of the bearing from the trunnion which leaves the platform141 free to be removed from the cabinet. On the plate 20 is a guide rib25 for the plate 21.

The connection between the top 13 and the platform 14 comprises thefollowing parts:

On the under side of the top 13 is secured a plate 26 having a dependingflange 27 provided with a curved slot 28 running in a direction from thefront to the rear of the cabinet. On the wall 12 is also` ful crumed,intermediate its ends as shown at 29, a lever 30 having one of its endsconrolling contact with the angle bar or strip 16. lt will be understoodthat two levers and associated parts will be provided, one for each endof the platform 14. On the side wall 12 is a roller 34- which seats inthe slot 28.

Then the top 13 is up and in position to serve as a desk top, as shownin Fig. 1, the roller 3a is at the rear end of the slot 28, and theroller 33 is beneath the platform ll about midway between its front andrear edges. The lever extends obliquely with respect to the platform14:, the connection 31 with the top 13, through the flange 27 of theplate 2G being near the rear end of the top. T he pivot of the platform14C is at its forward end. If now the top 13 is pressed downwardly itswings into the cabi net and assumes a vertical or upright positiontherein, and at the same time, the lever 30, through the roller 33,elevates the platform li to a horizontal position, as shown in Fig. 2.As the top 13 swings downwardly it is guided by the roller 34 in theslot 28. rl`he downward swing of the top 13 causes the lever 30 to turnon its fulcruni 29 and its end carrying the roller 33 swings upwardly.The roller 33 is loose in the curved slot 32 and slides downwardly7therein arriving at the lower end of the slot when the lever reaches thelimit of its swing and the platform 14 is in horizontal position. Theparts therefore work easily and do not bind.

The forward end of the top 13 has the usual depending front wall 35seating on a cross rail 35 when the top is up, and between this crossrail and the bottom 10 of the cabinet ext-ends a front wall 37 to eX-elude dust and dirt from the interior of the cabinet.

The platform 1411215 upstanding side walls 38 and a rear end wall 39.

On the side walls 12 of the cabinet are stops .l0 on which the top 13rests when it is up in horizontal position, and on the bottom l0 is ablock or rest 41 for the top 13 when it is swung into the cabinet asshown in Fig. 2.

I claim:

1. In a typewriter cabinet, a swinging top, a pivotally supportedtypewriter platform, and a lever fulcrumed intermediate its ends to thewall of the cabinet, said lever having a connection at one end with thetop, and a slidable connection at its opposite end with the under sideof the platform, said slidable connection being a roller carried by thelever, and said lever having a slot in which the roller is free toslide.

2. In a typewriter cabinet, a swinging top, a pivotally supportedtypewriter platform, a slotted plate secured to the top, a leverfulorumed intermediate its ends to the wall of the cabinet, said leverhaving a connection at one end with the slotted plate, and a slidableconnection at its opposite end with the under side of the platform, andguiding means on the top and the wall of the cabinet, said guiding meansbeing a roller on the wall of the cabinet seating in the slot of theplate.

In testimony whereof I aliix my signature.

MARTIN P. CONNOLLY.
